Wiring Requirements

Preferred Connection

This product is for use on a nominal 120 VAC circuit and has a

grounding plug that looks like the plug illustrated. Using a

higher voltage circuit is dangerous and may result in a ﬁre or

other accident.

house wiring, attaching the adaptor grounding screw tab to the

cover screw will NOT ground the unit. If there is any doubt

whether the cover screw is grounded, have it checked by a qualiﬁed

electrician or service professional.

A temporary connection with a two-prong adaptor may be made

where local codes permit, provided that the adaptor is grounded.
